Ikati. yi-UE-Category. Ngokwenkcazo ye-3GPP, i-UE-Category ihlukaniswe ngamanqanaba e-10 ukusuka kwi-1 ukuya kwi-10.
I-Cat.1-5 ichazwa yi-R8, i-Cat.6-8 ichazwa nge-R10, kunye ne-Cat.9-10 ichazwa nge-R11.
I-UE-Category ichaza ubukhulu becala i-uplink kunye ne-downlink rates ukuba izixhobo ze-terminal ze-UE zinokuxhasa.
Yintoni i-LTE Cat.1?
I-LTE Cat.1 (igama elipheleleyo yi-LTEUE-Udidi 1), apho i-UE ibhekisela kwisixhobo somsebenzisi, esiluhlelo lwentsebenzo engenazingcingo yesixhobo se-terminal somsebenzisi phantsi kwenethiwekhi ye-LTE. I-Cat.1 kukukhonza i-Intanethi yeZinto kunye nokuqonda ukusetyenziswa kwamandla aphantsi kunye nexabiso eliphantsi loxhumo lwe-LTE, olubaluleke kakhulu kuphuhliso lwe-Intanethi ye-Intanethi.
I-LTE Cat 1, ngamanye amaxesha ikwabhekisela njenge-4G Cat 1, yenzelwe ngokukodwa u-Machine-to-Machine (M2M) izicelo ze-IoT. Itekhnoloji yaqala yaziswa kwi-3GPP Release 8 kwi-2009 kwaye iye yaba kumgangatho oqhelekileyo we-LTE IoT iteknoloji yonxibelelwano ukususela ngoko. Ixhasa isantya esiphezulu se-downlink ye-10 Mbit / s kunye ne-uplink speed ye-5Mbit / s kwaye ikholelwa ukuba isisombululo esifanelekileyo seemeko ezingaxhomekeke kwi-high-speed data transmission kodwa zifuna ukuthembeka kwenethiwekhi ye-4G. Inokubonelela ngokusebenza kakuhle kwenethiwekhi, ukuthembeka okukhulu, ukhuseleko olukhuselekileyo kunye nokusebenza kweendleko ezifanelekileyo.
I-LTE Cat.1 vs LTE Cat.NB-1
Ngaphantsi kweemfuno zezicelo ze-IoT, i-3GPP Release 13 ichaza imigangatho yeCat M1 kunye neCatNB-1 (NB-IoT) ukuhlangabezana neemfuno zeemarike ze-IoT ezisezantsi kunye nezinga eliphantsi ngokulandelanayo. Izibonelelo zobugcisa ze-NB-IoT zinokuhlangabezana ngokupheleleyo neemfuno zeemeko ezisezantsi zomgangatho. Kodwa ngakolunye uhlangothi, isantya kunye nokuthembeka kwe-LTE Cat M ayilungile njengoko kulindelekile ekujonganeni neemfuno ze-IoT zezixhobo ezinxitywayo, iikhamera zokucupha, kunye nezixhobo zokulandela umkhondo, ukushiya umsantsa wobugcisa kwintsimi yoqhagamshelwano lwe-IoT ephakathi. .
Nangona kunjalo, i-LTE Cat.1 isekela i-10 Mbit / s i-downlink kunye ne-5Mbit / s isantya se-uplink, efikelela kumazinga aphezulu edatha ukuba i-LTE Cat M kunye ne-NB-IoT iteknoloji ayinakuze iphumelele. Oku kuye kwatyhala iinkampani ezininzi ze-IoT ukuba ngokuthe ngcembe zisebenzise itekhnoloji ye-LTE Cat 1 esele ikhona.
Kungekudala, i-Feasycom iqalise i-LTE Cat.1 imodyuli engenazintambo ye-FSC-CL4010, inokusetyenziswa ngokubanzi kwi: i-smart wear, i-POS, iprinta ephathekayo, i-OBD, isixhobo sokuxilonga imoto, indawo yemoto, izixhobo zokwabelana, inkqubo ye-intercom ehlakaniphile kunye nokunye.
